It states conduit middle part 102 and extends to the tail end 103 from front end 101, and the middle part 102 is at least partly bent, and is made
It obtains the conduit 100 and forms a conduit for having certain radian.When medical staff's single hand grip is performed the operation, the tail end of conduit
Portion 103 will deviate at patient's earhole, thus, it is possible to sufficiently expose surgical field of view, rapidly and accurately be placed into convenient for ventilation duct
Position.
In one of the embodiments, as depicted in figs. 1 and 2, the seal wire 200 has front end bulb 201, before described
The outer diameter of bulb 201 is held to be greater than the internal diameter of the ventilation duct.Ventilation duct before surgery, can be placed on described lead by medical staff
In pipe front end 101, when setting pipe, medical staff pushes seal wire to move forward along conduit cavity, and seal wire front end abuts the ventilation duct simultaneously
Ventilation duct is pushed into operation implant site.Therefore, front end bulb 201 is arranged in 200 front end of seal wire in the utility model, no
Can only guarantee ventilation duct during Forward will not run-off the straight will not be by ventilation duct while in 200 reseting procedure of seal wire
Mistakenly take back.
In one of the embodiments, as shown in Figure 1, the front end bulb 201 by 200 front end of seal wire with seal wire 200
Axis is the center of circle, is extended spirally in the same plane, and 201 outer rim of front end bulb is adjacent to the pipe inner wall.This
Front end bulb 201 described in utility model is for example integrally formed with the seal wire 200, and the front end bulb 201 can use
By seal wire 200 using 100 axis direction of conduit as the center of circle, extend spirally in the same plane.Wherein front end bulb 201
The inner wall of conduit 100 can be close to or be abutted to outer rim, be formed between the front end bulb 201 and the ventilation duct as a result,
One biggish contact surface, while can have certain elasticity, it is described under outside pulling force effect especially in reseting procedure
Front end bulb 201 can occur to deform slightly, be convenient for 200 Rapid reset of seal wire.
In one of the embodiments, as depicted in figs. 1 and 2, at least partly bending of the middle part 102, so that institute
The axis of the axis and the tail end 103 of stating catheter proximal end portion 101 forms the angle of 100-160 degree.So that described lead
Pipe 100 has the radian of 100-160 degree, sufficiently exposes surgical field of view.Wherein it is preferred that the radian of the conduit is 135 degree,
It is not only convenient for medical staff's grip, while can sufficiently expose surgical field of view.
In one of the embodiments, as shown in Figure 1, the tail end of the seal wire 200 is connected with control ring 202.It is performing the operation
In the process, conduit described in medical staff's single hand grip, while little finger of toe can be placed in control ring 202, utilize pushing away for little finger of toe
It draws and seal wire 200 is pushed to move forward or reset along conduit cavity.The control ring 202 ensure that medical staff singlehanded can carry out hand
Art.
In one of the embodiments, as shown in Figure 1, being provided with positioning groove 104 on the pipe inner wall, the positioning
Groove 104 is located at the joint of the front end 101 and the middle part 102, and the front end bulb 201 is under external force promotion
When being moved to the positioning groove 104, the outer rim of the front end bulb 201 is accommodated in the positioning groove 104.It is described fixed
Position groove 104 is in close 101 side of front end, such as has the front end side wall perpendicular to the catheter wall, and close to intermediate
The rear end side wall of 102 side of portion and the angle of the pipe inner wall are no more than 30 degree.As a result, when the front end bulb of the seal wire
201 when moving forward in the positioning groove 104, and the front end side wall can prevent it from further moving forward；Playing prevents seal wire 200 from moving
It is dynamic excessive.When seal wire 200 resets, medical staff retracts seal wire by control ring 202, and the front end bulb 201 can occur
Appropriate deformation, is pulled easily then along the rear end side wall of positioning groove 104.
In one of the embodiments, as shown in Figure 1, the internal diameter of the conduit is no more than 2.5mm, the diameter of the seal wire
No more than 2.0mm.It is limited by operative segment, the internal diameter of the conduit 100 is 2.5mm, and the diameter of the seal wire is that 2.0mm is
It is optimal.
The seal wire 200 is made of Metal wire material in one of the embodiments,.The seal wire 200 is also possible to have
There are the plastics of some strength to be made, the seal wire 200 can move forward along the inner cavity bendable of conduit 100.
In one of the embodiments, as shown in Figure 1, being additionally provided with brake component 203 on the seal wire 200, the braking
Part 203 is arranged in 202 upstream of control ring, and the brake component 203 is located at other than the conduit 100, when the seal wire 200 will
After ventilation duct is pushed into eardrum, the seal wire 200 is braked.The brake component 203 is, for example, to set perpendicular to 200 axis of seal wire
The sheet shaped piece set has a diameter larger than the outer diameter of the conduit 100, when the brake component 203 submits tail end of conduit, plays braking
The effect that seal wire 200 moves forward further prevents overexertion that seal wire 100 front end of conduit of scurrying out is caused to damage patient.
In one of the embodiments, as shown in Figure 1, the Tube adapter for drum membrane further include: handle 300 is arranged in institute
It states on 100 outer wall of conduit, the handle 300 is annular in shape, is welded on the tail end 103.The handle 300 is used for medical care people
Thumb is put into it by member, keeps the stability of conduit 100 in the course of surgery.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
